The present invention relates to window construction and particularly tothe construction of'casement windows.

Among'the objects of the invention is a casement window and frameprovided with a hinge which causes the window to be moved bodily awayfrom the adjacent side of the frame for either ventilation or cleaningpurposes.

Other objects will readily appear to those skilled in the art uponreference to the following description and accompanying drawing, inwhich Fig. 1, is a perspective view of a window sash and frame embodyingthe invention.

Fig. 2, is a section on line 22 of Fig. 1

Fig. 3, is a section on line 33 of Fig. 2. 'As shown, the window frame10 is preferably of Z-sectionmetal members cut and welded to rectangularshape so as to present on its inner face an inwardly extending flange 11and on its outer face an outwardly extend- 1 ing flange 12.

@The sash 15 or window proper is also made in the usual manner bywelding suitable projecting arm 21 which in turn is carried by a'flatportion 22 adapted to be secured as by screws 23 to the sash 15. e Pin20 has a bearing in a block 25 adapted to slide in a slotted guide block26 secured to frame 10 as by screws 27. It is preferred also to providemeans for regulating the slid- F ing of block 26 so that, while the sash15 may be easily swung open and shut, it will remain many partly openposition without additlonal securing means. This accomplished by aplate28 secured to block 26 and extending over block 25. Through the securingscrews 29, adjusted pressure may be put on block 2550 as to causesufficient friction thereon to hold the sash in any desired position.

The upper hinge pin may be similarly made and mounted but'preferablycooperates directly with a suitable guide carried by frame 10,eliminating parts similar to block 25 and guide 26.

, Carried also by frame 10 is a U-shaped member or controlling bail 30hinged to frame 10 as at 31 and adapted to lie in the channel formedbetween flange 11 and the outer flange of the sash when the latter isclosed.

The free ends of bail 30 are hinged to the sash'by means of bolts 32 atsuch a distance from the lineof the hinge pins as will produce thedesired translation of the sash. This distance in the form shown isabout one-fourth of the width of the sash. The free arms of bail 30 are,of course, of less length than the width of the sash by the distancefrom bolt 32 to the adjacent edge of the sash.

The operation of the present device is easily seen from the drawing. Inopening the window, the sash will swing on the hinge pins and the bail30, acting as a fulcrum, will cause the pins to move laterally towardthe center line of the frame, suitable stops (not shown) being of courseprovided. By using the form of controlling bail shown, both ends of thesash areconstrained to move together so that the hinge pin alignment isalways maintained.

Now having described the invention and the preferred form of embodimentthereof, it is to be understood that the said invention is to belimited, not to the specific details herein set forth but only by thescope of the claims which follow.

I claim:

1. In a casement window, a sash having upper and lower hinge pins, aframe having slidably mounted bearings for said pins, said bearingspermitting lateral and pivotal movement of said pins, and a rigid Ushaped bail hinged at its intermediate portion .to said frame on theside opposite to the closed window position of said hinges and havingarms integral therewith and hingedly connected to the sash at top andbottom respectively and at points spaced from said pins to constrainboth hinges to likemovement in v said frame. 7 V

2. In a casement Window, a sash having upper and lower hinge pins, aframe having bearings for said pins, at least oneof said loearingsconsisting of a block slidaloly mounted in a guide in said frame, bothof said bearings permitting lateral and pivotal movement of-said pins,and a rigid U shaped bail hinged at its intermediate. portion to saidframe on the side opposite to the closed window portion of said hingesand having arms'integral therewith and hingedly connected to the sash.at topand bottom respectively and at points spaced from said pins, toconstrain both hinges tolike movement in said frame.

3. In a casement window, a sash having 23 upper and lower hinge pins, aframe having bearings for said pins, at least one of said bearingsconsisting of a block slidably mounted in a guide in said frame,adjustable means forholding the slidableblock in any desired a; positionin the guide, both of said bearings permitting lateral and pivotalmovement of said pins and a rigid U shaped bail hinged at itsintermediate portion to said frameon the side opposite to the closedwindow por- 59 tion of said hinges and having arms integral therewithand hingedly connected. to the sash at top and bottom respectively andat points spaced from said pins, to constrain both hinges to likemovement in said frame. 55 HERBERT E.
